turned off.
• It is recommended that a qualified electrician is consulted or used for
the installation of this luminaire and install in accordance with the
current IEE wiring and Building Regulations.

4. Installation Advice
• The motion detector has a number of detection zones, at various vertical
and horizontal angles as shown (see Image A).
• A moving human body needs to cross/enter one of these zones to activate
the sensor. The best all-round coverage is achieved with the unit mounted
at the optimum height of 1.8m.
• Careful positioning of the sensor will be required for optimum performance
(See Image A).
• The sensor is more sensitive to movement ACROSS its field of vision than
to movement directly TOWARD (See Image B). Therefore position the unit
so that the sensor looks ACROSS the likely approach path.
• Avoid positioning the sensor where there are any sources of heat in the
detection area (extractor fans, tumble dryers etc.).
• Reflective surfaces (i.e. pools of water or white-painted walls) and overhanging
branches may cause false activation under extreme conditions.
• During extreme weather conditions the motion sensor may exhibit unusual
behaviour, this does not indicate a fault with the sensor. Once normal weather
conditions return, the sensor will resume normal operation.

5. Installation
5.1 Ensure the mains supply is switched off and the circuit supply fuses
are removed or the circuit breaker turned OFF.
5.2 An isolating switch should be installed to the switch the power ON
and OFF to the luminaire. This allows the unit to be easily switched OFF
for maintenance purposes.
5.3 Carefully remove the diffuser using a Philips terminal screwdriver to release
the clips located both sides of the bulkhead light (See diagram E).
5.4 Remove the connection cover by undoing the fixing screw that holds
it in place (See diagram F).
5.5 Ensure the bulkhead is in an upright position with the sensor at the bottom
of the bulkhead.
5.6 Mark the position of the mounting holes on the wall using the wall plate
as a template and drill the holes ensuring not to infringe with any gas/water
pipes or electrical cables that may be hidden below the surface. Insert the
rawl plugs into the holes.
5.7 Pierce the pre-installed grommet and pass through the 230V AC 50Hz
mains supply cable ensuring that the IP rating of the fitting is maintained
(silicon sealant may be used).
5.8 Secure the back plate to the wall using the correct mounting screws
for the rawl plugs installed. Do not overtighten the screws as this could
damage the wall plate.
5.9 Connect the 230V AC 50Hz mains supply cable to the terminal block
ensuring that all bare conductors are sleeved and that correct polarity
is observed (See section 6. Connection Diagram).
5.10 Re-attach the connection cover and secure using the fixing screw
previously removed in step 5.4.
5.11 Install the light bulb (not supplied).
5.12 Fit the diffuser back onto the main body of the unit, ensuring it clicks
firmly into place.

• The diagram below also shows the required connections for the addition
of slave luminaires. When adding slaves, be sure not to exceed the
Total Switchable Loads (see section 3. Technical Specifications).
7. Operation & Testing
Walk Test Procedure
• The adjustment knobs located beneath the sensor head (see diagram “C”)
are factory set to “Walk Test Mode” i.e. LUX set to the ‘Sun’ symbol and the
TIME set to the minimum.
• The sensor will rotate from left to right. Adjust the sensor head to the desired
direction for best coverage.
• Turn the power to the unit ON. The lamp will illuminate for approximately
1 to 2 minutes. This indicates the unit is wired correctly and the unit is in
Test Mode. Try to remain outside the detection area during the warm-up period.
Test Mode
• The lamp will now illuminate for approximately 5 seconds every time movement
is detected.
• Walk across the detection area approximately 5 metres from the unit.
Each time you are detected the lamp will illuminate. Now stand still until
the lamp extinguishes (this should take approx. 2 seconds).

• Start moving again, when you are detected again the lamp will illuminate.
• Repeat the above, walking at various angles and distances to the unit.
This will help you to establish the detection pattern.
Setting up for Automatic Operation
• When the walk tests are complete, the unit can be set up for
automatic operation.
• The TIME setting controls how long the unit remains illuminated following
activation, and after all motion ceases (See diagram “C”).
• The minimum time (fully anti-clockwise) is approx. 5 seconds, whilst the
maximum time (fully clockwise) is approx. 5 minutes. Set the control to the
desired setting between these limits.
• The LUX control determines the level of darkness required for the unit to start
operating. The setting is best achieved by the procedure below (See diagram “C”.
The LUX adjustment knob is indicated by the ‘Moon’ and ‘Sun’ symbols);
1. Set the LUX control knob fully clockwise.
2. When the ambient light level reaches the level of darkness at which you wish
the lamp to become operative (i.e. at dusk) SLOWLY rotate the control in an
anti-clockwise direction until a point is reached where the lamp illuminates.
3. Leave the control set at this point.
• At this position the unit should become operative at approximately the same
level of darkness each evening.
• Observe the operation of the unit. If the unit is starting to operate too early
(i.e. when it is quite light) adjust the control slightly anti-clockwise.
If the unit starts to operate too late (i.e. when it is very dark). Adjust the
control slightly clockwise.
• Continue to adjust until the unit operates as desired.
Masking the Sensor Lens
• To reduce the sensor coverage, preventing detection in unwanted areas, mask
the sensor lens using electricians tape or something similar (see diagram D).
• The top section of the lens covers long range detection, the bottom covers
short range. Similarly the left and right lens sections cover the left and right
detection areas respectively.

8.Troubleshooting
Problem
• Lamp stays ON all
the time at night
• The PIR sensor
keeps activating
for no reason/
at random
• The PIR sensor will
not operate
at night
• The unit activates
during the daytime
• The PIR sensor will
not operate at all
Solution
The unit may be suffering from false activation. Cover
the sensor lens completely with a thick cloth. This will
prevent the sensor from ‘seeing’ anything. If the unit now
switches off after the set time duration and does not
re-activate, this indicates that the problem was caused
by false activation. The problem may be solved by slightly
adjusting the direction/angle of the sensor head
(See section 7. Operation & Testing).
Occasionally, winds may activate the sensor. Sometimes
passages between buildings etc. can cause a ‘wind
tunnel’ effect. Ensure the unit is not positioned so as to
allow detection of cars/people using public thoroughfares
adjacent to your property.
The level of the ambient light in the area may be too
bright to allow operation at the current LUX setting.
During the hours of darkness, adjust the LUX control
slowly clockwise until the lamp illuminates (See section
7.Operation & Testing).
The level of ambient light in the area may be too dark for the
current LUX setting. During daylight, adjust the LUX control
slightly anti-clockwise. When the lamp load extinguishes,
enter the detection area. If the PIR still activates, the setting
is still too high. Repeat the above procedure until the PIR
does not activate when you enter the detection area.
Refer to previous section for more details.
Check that the power is switched ON at the circuit
breaker/internal wall switch.
Turn OFF the power to the unit and check the wiring
connections as per the diagram (See section 6.
Connection Diagram). Ensure no connections are loose.
Check the lamp. If the lamp has failed, replace. Ensure
that the lamp is seated correctly in the lamp holder.

• The PIR sensor
coverage is
poor/sporadic
• The detection
range varies from
day to day
The unit may be poorly located (See section 4. Installation
Advice) and may need to be moved.
PIR sensors are influenced by climatic conditions.
The colder the ambient temperature, the more effective
the sensor will be. You may need to make seasonal
adjustments to the sensor head position to ensure
trouble-free operation all year round.
